Answer:
Atherosclerosis affects arteries, these blood vessels are elastic and flexible in order to allow good blood circulation
Explanation:
The blood vessels are classified into three types: arteries, veins, and capillaries. An artery is a muscular blood vessel that is able to carry blood away from the heart to different parts of the body. Healthy arteries need to be elastic and flexible in order to adjust their diameter and thus control blood flow by maintaining blood pressure. Arteriosclerosis is a chronic disease caused by the accumulation of fatty substances (especially cholesterol) in the artery walls, thereby difficulting blood circulation by thickening and hardening these walls.
